EtherCAT master TODO
$Id$
-------------------------------------------------------------------------------
* Release 1.3:
- Remove ecrt_master_run(). Make master FSM run in process context instead.
- Remove addressing scheme "X:Y".
- Allow only MAC address as device ID.
- Remove ugly ec_slave_is_coupler().
* Future features:
- SDO dictionary and -access in operation mode.
- SDO write access in sysfs.
- Speed up IDLE-FSM through fast mode with schedule().
- Evaluate EEPROM contents after writing.
- Interface/buffers for asynchronous domain IO.
- Distributed clocks.
- Read dynamic PDO mapping from SDO dictionary (see can-cia.org: cia301ds4).
- Redundancy with 2 network adapters.
- Interface for alternative PDO mapping.
- Read out CRC counters.
- Optimize alignment of process data.
- Calculate expected working counter for domains.
* Smaller issues:
- Simplify FSMs with <state>_enter() functions.
- Dynamic creation of EoE handlers.
- Output intermediate results during lsec.
- State change FSM: Follow spontaneous state changes.
* Less important issues:
- Implement all EtherCAT datagram types.
- File access over EtherCAT (FoE).
- Allow VLAN tagging.
- Determine number of frames the NIC can handle.
